HENRY G. VOIGHT, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO RUSSELL & ERWIN MANUFACTURING COMPANY, CONNECTICUT.

OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF LOCK.

No. 908,43 l.

Application filed February 15, 1908.

To all whom 'it may concern:

Be it lmown that I, HENRY G. VoieHT, a citizen of the United States, residing at N ew Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in locks of the so-called cylinder type, the object of the invention being to simplify and cheapen the cost of production without sacrificing the J c pciality, efficiency or durability of the same.

Another object of the invention comprises the provision of an adjustable feature whereby the cylinder may be connected to loch cases fitted to doors of different thicknesses.

In the drawings, `Figure l is a side elevation of the complete cylinder', slightly enlarged, the parts being arranged for approximately the minimum adjustment; llig. 2 is a similar view showing approximately the maximum adjustment, Fig. 3 is a vertical longitudinal section of Eig. l, certain parts being shown in elevation; l'ig. 4 is a horizontal sectional view of llig. 2, certain parts being shown in elevation 5 llig. 5 is a view of the inner end of the loch; Fig. 6 is a view of the outer end of the loclr, partly brolren away Fig. 7 is a section on the plane of the line fc-x of li'ig. 3, looling to the left llig. 8 is a section on the plane of the same line, looking to the right lligs. 9 and 10 are different elevations of the same detail; lf'ig. ll is a front end view of another detail.

l represents the face plate of the usual disk-like outline. If desired, this face plate may have an external scalp or lining applied thereto, as indicated in section, Fig. S.

2 is the cylinder casing, the forward end of which is mounted inthe face plate l. IWithin the cylinder casing is the plug 4 is the tumbler casing connected with the cylinder casing 2 and carrying the usual tumblers (not shown). The tumbler casing is preferably provided with a forward projection 5, which is also connected with the face plate l and may be riveted, as shown, thus firmly securing together the parts l, 2 and 4, thus constituting a frame. The tumbler casing has lateral offsets 6 6, which extend longitudinally thereof to provide bearings for the purpose hereinafter described.

7 is a hollow cylindrical shell, which is provided With internal brace plates 8 8 ex- Specicaton of Letters Patent.

tending longitudinally thereof, each of which brace plates in turn is shaped to provide a grooved bearing 9 arranged to slide upon the guide offsets 6 6. inder 7 is closed by an end plate 10. The brace plates 8 8 may be secured in any desired manner within the cylindrical shell 7, and, if desired, may be riveted to the end plate l0, as shown in Fig. 5.

From the foregoing it will be seen that the hollow shell portion 7 may be slid to and fro relatively to the face late l. To provide a superior support anc adjustment, a guide pin ll is preferably provided, the same being carried by the end plate l0 and projecting into a longitudinal bore in one of the offsets 6. The end plate l0 also carries an adjusting screw l2, the forward end of which likewise projects into a threaded bore in the other offset 6 (see Figs. 3 and 4). While the reinforcing plates 6 6 furnish a satisfactory guide for the shell, greater strength is secured by adding the guide pin ll and the screw l2. Furthermore, by the provision of the screw l2, any desired adjustment may be easily effected and the shell 7 may be xed at any desired position relatively to the face plate l. Rotatably mounted on the end late 10 is a roll-bach 14, the same being Acoated in proper alinement with the lug 3. At the end of the plug 3 is a cap-p ate l5 carrying a rearward connecting bar or coupling 16, of irregular cross-sectional outline, arranged to make a sliding connection with the roll-back 14. As originally constructed, this coupling varm 16 may be of the maximum length to which the cylinder may be adjusted. Vlfhen the parts have been adjusted to their final position (depending upon the thickness of the particular door to which the cylinder'locl is to be applied), any part of the coupling arm 16 that projects to the rear of the roll-back (as indicated by dotted lines Figs. 3 and 4) may be cut off.

From the foregoing it will be seen that the construction, as a whole, is extremely light and yet quite as serviceable and edective as though it were solid. By this arrangement much sheet or wrought metal may be effectively employed. By providing for the adjustment of the shell 7, the lock has a universal application, since it is possible to apply it to doors of the maximum as well as the minimum thickness.

Y In order to move the shell 7 in both direc- The rear end of the cyl-l tions by the adjusting screw 12, I preferably rovide a collar 12EL just inside of that part of the shell through which the screw passes, which collar may be secured to the screw in any desired manner, sufficient freedom being provided to ermit the screw to turn freely 1n the end pilate 10. A similar collar may likewise be rovided on the guide 1l, although in t iis instance it is immaterial whether the guide pin turns. The end plate 10 is preferably countersunk, so that the heads of the guide-pin 11 and screw 12 will lie flush. In one or both sides of the shell 7, a longitudinal groove 17 may be provided to receive the set screw (not shown) carried by the lock case to which the cylinder lock is to be applied.

1a is a centering shoulder on the rear of the face plate 1, the same being of substantially the same diameter and outline as the shell 7,

, theifiinction of said centering shoulder being to steady the face plate in the opening in the bore, through which the shell is passed when the lock is applied.

It should be understood that the terms roll-back and key-plug are conventionj ally employed and are intended to include the substitution of equivalent devices. It should also be understood that the particular tumbler construction employed is immaterial to this invention.
